Abstract
The utility model provides a bridge crane used for low plants, relating to bridge cranes and solving the technical problem that the total heights of conventional cranes can not meet the low plant requirement. The bridge crane comprises a bridge, cart travel mechanisms, a trolley frame, a hoisting mechanism, trolley travel mechanisms and cart travel tracks, wherein the bridge is formed by left and right box girders; the cart travel mechanisms are installed below the four corners of the bridge; the hoisting mechanism is installed on the trolley frame; the trolley travel mechanisms are installed below the trolley frame; the cart travel tracks are installed on rail-bearing girders of a plant; left and right trolley travel tracks are installed on the inner sides of the left and right box girders respectively; the bottom surface of the hoisting mechanism installed on the trolley frame is lower than the upper plane of the trolley frame. The bridge crane is used in the special occasions of plants of hydropower stations, and has the advantages of reasonable structure and low cost.
Description
Technical field
The utility model relates to crane in bridge type, is particularly suitable for the occasion that factory building height is low, for example the crane in bridge type of power station water turbine factory building.
Background technology
In power station, a lot of factory buildings are all on mountain, to dig cavern to build, and powerhouse of hydropower station hoisting crane requires bottom-to-top-height low for this reason.The girder end face of conventional hoisting crane is a horizontal surface, and trolley travelling track is arranged on girder end face, and monkey can move within the scope of whole girder.Owing to being subject to the restriction of material Strong degree, the height of crane girder has minimum limit value, and therefore, the bottom-to-top-height of conventional hoisting crane can not meet the requirement of present powerhouse of hydropower station.
Utility model content
The purpose of this utility model is intended to overcome the shortcoming of prior art, and a kind of crane in bridge type for low factory building is provided, and the bottom-to-top-height that solves conventional hoisting crane can not meet the technical matters that the low factory building in power station requires.
The utility model is achieved through the following technical solutions:
A kind of crane in bridge type for low factory building, comprise: crane span structure, traveling mechanism of the larger traveller, trolley frame, lifting mechanism, wheeling mechanism, cart orbit, crane span structure consists of left box type girder and right box type girder, traveling mechanism of the larger traveller is comprised of four groups of eight wheels, be arranged on respectively the below at four angles of crane span structure, trolley frame is a rigid frame structure, lifting mechanism is installed above, the wheeling mechanism being comprised of four wheels is installed in four jiaos of belows of trolley frame, whole dolly is arranged on trolley travelling track, cart orbit is arranged on the support rail beam of factory building, it is characterized in that: left trolley travelling track and right trolley travelling track are installed respectively in the inner side of described left box type girder and right box type girder, the bottom surface of lifting mechanism is installed on described trolley frame, will be lower than the upper plane of trolley frame.
The utility model compared with prior art, because the trolley travelling track of hoisting crane is installed on the inner side of two girders, lifting mechanism bottom surface is arranged under the upper plane of trolley frame, not only greatly reduce the height of hoisting crane car load, also greatly reduce crane height more than crane track absolute altitude, also greatly reduce the height of factory building, reduced the total cost of hydropower project.
The utility model is for the special occasions of powerhouse of hydropower station, have rational in infrastructure, the advantage that cost is low.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation (front view) of the crane in bridge type for low factory building;
Fig. 2 is the lateral plan of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, by preferred embodiment, the utility model is described in further detail.
As Fig. 1, shown in 2, a kind of crane in bridge type for low factory building, comprise: crane span structure 1, traveling mechanism of the larger traveller 2, trolley frame 3, lifting mechanism 4, wheeling mechanism 5, cart orbit 6, crane span structure 1 consists of left box type girder 1-1 and right box type girder 1-2, traveling mechanism of the larger traveller 2 is comprised of four groups of eight wheels, be arranged on respectively the below at four angles of crane span structure 1, trolley frame 3 is a rigid frame structure, lifting mechanism 4 is installed above, the wheeling mechanism 5 being comprised of four wheels is installed in 3 four jiaos of belows of trolley frame, whole dolly is arranged on trolley travelling track, cart orbit 6 is arranged on the support rail beam of factory building, left trolley travelling track 1-3 and right trolley travelling track 1-4 are installed respectively in the inner side of described left box type girder 1-1 and right box type girder 1-2, the bottom surface of on described trolley frame 3, lifting mechanism 4 being installed, will be lower than the upper plane of trolley frame 3.
Because the setting height(from bottom) of lifting mechanism 4 reduces, therefore the whole height of dolly decreases; Because left trolley travelling track 1-3 and right trolley travelling track 1-4 are arranged on the inner side of left box type girder 1-1 and right box type girder 1-2, rather than at girder top, the also corresponding reduction of the car load height of hoisting crane.So just realized the object that greatly reduces hoisting crane car load height, also greatly reduced crane height more than crane track absolute altitude, met the requirement of powerhouse of hydropower station simultaneously.
